Minecraft XBLA adding DLC costumes

Minecraft on Xbox Live Arcade has always had a conspicuous "Download Content" option on the main menu. But right now, it just leads to a quick message saying none is available. What kind of DLC can we expect from this game? Apparently the answer is costumes.

OXM reports that the first content pack will add a set of 40 costumes. Some that we've seen so far include Xbox icons like a Covenant Grunt, Trials biker, and Splosion Man. You could also be a king, if you have a giant ego, or a Creeper, if you want to run straight towards your friends to freak them out. A free trial will apparently be available too, though its contents haven't been disclosed.
